Rynerson noted that Estacada is growing at a faster rate than similarly sized cities in Oregon, which he attributed to its proximity to the Portland metro area.

"It definitely has a location advantage compared to other places," Rynerson said. "Places Estacada's size in Eastern and Southern Oregon are definitely not growing as fast as Estacada."

Across Clackamas County, 8,020 residents were gained, bringing the population from 404,980 to 413,000. In total, Oregon's population went from 4,076,350 in 2016 to 4,141,100 in 2017, representing an increase of 64,750 residents.

In a news release, Rynerson noted that, "because of an aging population and declining birth rates, natural increase now contributes less to Oregon's population growth than at any time since the 1930s."

Conversely, net migration in Oregon has accelerated, with the number of people moving to the state exceeding those moving out by more than 50,000 for two years in a row.
